Device equipped with a sensor

1. A device ( 10 ) with a sensor for detecting data, wherein the device is guided with one hand ( 20 , 22 ) over a surface ( 14 ) by a thumb and at least one other finger of an operator and in which the data detected are displayed by a display unit ( 38 ), characterized in that grasping surfaces ( 40 , 42 ) for be hand ( 20 , 22 ) are positioned on two approximately diametrically opposed sides of a grip ( 12 ), at least one of which sides has a sensor ( 26 , 28 , 30 , 32 ) that detects the number of fingers ( 20 , 22 ) resting against this grasping surface ( 40 , 42 ), wherein at least one of the grasping surfaces has a further sensor, wherein the further sensor is activatable by the thumb of the operator, wherein the device switches between left-handed and right-handed manipulation, wherein the device ( 10 ) switches the content of the display device ( 28 ) between a left-handed and right-handed representation depending on the number of the fingers ( 20 , 22 ) identified.

2. The device ( 10 ) according to claim 1 , wherein two neighboring contact strips ( 26 , 28 or 30 , 32 ) are provided as sensors ( 26 , 28 , 30 , 32 ) and the resistance of a measuring circuit ( 34 , 36 ) that is closed by the fingers ( 20 , 22 ) evaluated by means of an evaluation unit ( 24 ).

3. The device ( 10 ) according to claim 2 , wherein the sensors ( 26 , 28 , 30 , 32 ) function according to a capacitive or inductive measuring method.

4. The device ( 10 ) according to claim 2 , wherein the sensors ( 26 , 28 , 30 , 32 ) are photoelectric sensors.

5. The device ( 10 ) according to claim 2 , wherein sensors ( 26 , 28 ; 30 , 32 ) are provided on opposite grasping surfaces ( 40 , 42 ), wherein the signals of the sensors ( 26 , 28 ; 30 , 32 ) of one grasping surface ( 40 , 42 ) are compared to signals of the sensors ( 26 , 28 ; 30 , 32 ) of the other grasping surface ( 40 , 42 ).
